CHE CK-VALVE Patented July 1 6, 1 907.

Application tiled January 16,1906. Serial No. 296,295.

To all whom it 'may concern:

Be it known that I, HENRY DANIEL, a citizen of the United States,residing at Crofton, in the county of Kalkaska and State of Michigan,have invented certain new and useful lmprovementsin Check-Valves; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to pumps and more particularly in improvements inthe valves whereby water can be easily hoisted, there being no parts inthe valves which are liable to get out of order and interfere with theirproper operation.

The invention consists of a check valve in the form of a ball which isnormally seated by gravity and which is surrounded by a sleeve whichprevents displacement of the ball. A lift valve is connected to the pumprod and consists of a head which is connected by yokes to the rod andinterposed between the yokes isa plate which is -normally seated overthe aperture formed within the head. Springs may be utilized forassisting gravity for automatically seating the plate and for preventingdisplacement thereof.

The invention also consists of the further novel features ofconstruction and combination of parts, the preferred form whereof willbe hereinafter made clearly apparent and pointed out inthe claims. Inthe accompanying drawings I have shown the preferred form o myinvention.

In said drawings-Figure 1 is a section through the pump cylinder andshowing my valves in position therein, and, Fig. 2 is a section throughthe lift valve on the line Fig. 1.

Referring to the figures by numerals of reference, 1 is a cylinderhaving heads 2 and 3 secured to the ends thereof, each head having apassage 4 and 5, respectively. The passage 5 has an internal shoulder Gwhich constitutes a seat for a ball 7 formed of rubber or other desiredmaterial and extending upward from the head 3 and surrounding the seatis a cylindrical sleeve 8, the internal diameter of which is somewhatgreater than the diameter of the ball 7. This sleeve may project intothe cylinder 1 any desired distance and has a retaining pin 9 extendingthereacross at its inner end so as to prevent the ball 7 from leavingthe sleeve.

A circular recess or trap 10 is formed around the sleeve 8 for thereception of any sediment which may accumulate` within the cylinder,said sediment being therefore held away from the seat 6 so as not tointerfere with the proper seating of the ball 7.

The pump 4rod 11 extends through the passage 4 in head 2 and its low erthreaded end projects into a sleeve 12 from Which extends a suitablenumber of angular arms or yokes 13 which are formed integral with a ring14 having a circular groove 15 in its upper face in which is disposed apacking ring 1G. The opening through the ring has its walls`screwthreaded to receive a tubular extension 17 formed around the opening ofa ring 18, and a washer 1.9 of leather or other suitable material isinterposed between the rings 1S and 14 and by rotating the ring 1S, thisextension 17 will screw into the ring 14 so that the washer 19 will befirmly clamped in position. The head constituted by the two rings 14 and18 and washer 19 supports a disk 20 having a depending lug 21 whichprojects into the extension 17 and serves to prevent lateraldisplacement of the disk. This disk has a circular groove 2l within itinto which projects spring lingers 22 which are suitably secured inrecesses 23 formed in the inner faces of the yokes 13.

It will be obvious that when the lift valve, which is formed of therings 14 and 1S and the disk 20, is raised, water will be sucked throughthe passage 5 and sleeve 8 and into cylinder 1, said action causing theball 7 to be unscatcd. During the reverse movement of the lift valve,the ball 7 will be seated so as to prevent the return of the water drawninto the cylinder 1 and this water will force the disk 20 upward andflow through the rings into that portion of the cylinder' above the liftvalve. When the lift valve again moves upward, the disk 20 will beseated by gravity assisted by the springs 22 and the weight of the waterabove the valve, and therefore all water above said valve will be forcedout through said passage 4.

1. The herein described piston, comprising a ring, yokes integral withsaid ring, a disk seated upon the ring and normally closing the openingtherein, said ring having a circular groove, spring fingers extendingfrom the yokes and sented in the groove, and means to reciprocate saidpiston.

2. The herein described piston comprising a ring, a plurality of yokesintegral with said ring, a disk seated upon the ring and normallyclosing the opening therein, said disk having a circular groove, springfingers extending from the yokes and seated in the groove, a flexiblewasher extending beyond the periphery of the ring, adjustable means forclamping the washer to the ring and additional means engaging the upperends of said yokes adapted to operate said piston.

S. The herein described piston comprising a ring having a threadedaperture therethrough, a plurality of yokes integral with and extendingupwardly from said ring, a second ring, a threaded extension thereonengaging thc walls of the threaded aperture, a flexible washerinterposed between the ring and extending therefrom, a groovcd disknormally seated upon the rings and closing the aperture therein, a lugdepending from the disk and within the aperture, spring lingersextending Afrom the yokes and seated within the groove in the disk andmeans to operate said piston.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses HENRY DANIEL.
